Abstract

A mechanism (10, 110, 210, 310, 410, 510, 610) for adjusting the orientation of vehicle headlamps includes a gear structure (18, 20) coupled to an adjusting member (12) adapted for securement (11) to the headlamp so that rotation of the gear structure imparts linear movement to the adjusting member (12) which adjusts orientation of the headlamp. The adjusting member can be either a translating rack (12, 112, 212) or a drive screw (312, 412, 512) and the preferred drive structure includes a worm drive gear (18, 118, 218, 318, 418, 518) which drives an adjusting gear (20, 120, 220, 320, 420, 520) operatively engaged to provide translation of the rack or the screw. The adjusting member (412, 512) can provide locking of two housing portions (415, 416; 515, 516) which enclose the gear structure. Prevailing torque on the gears (418, 420; 518, 520) as well as the adjusting member (412, 512) can be provided by the locking action of the adjusting member (412, 512) or a drive shaft (438, 538, 638) extending from the drive gear (418, 518).
